[PATCH] python/semanage/seobject: Fix listing boolean values

[Vit Mojzis]

Fix gathering boolean values by fixing always False if condition
(determining whether the values are listed from local store).

Fix listing boolean values by printing the correct values and not
forcing the use of security_get_boolean_active (which causes
crash when listing booleans that are not present in active policy).

Fixes:
    # dnf install selinux-policy-mls
    # cat > mypolicy.cil
    (boolean xyz false)

    # semodule -i mypolicy.cil -s mls

    # semanage boolean -l -S mls
    ...
    irssi_use_full_network         (off  ,  off)  Allow the Irssi IRC Client to connect to any port, and to bind to any unreserved port.
    mozilla_plugin_use_bluejeans   (off  ,  off)  Allow mozilla plugin to use Bluejeans.
    OSError: No such file or directory
